RE: Application for Discharge System — Clayton Property
7825 Beech Forest Road, Lewisville, NC 27023
Dear Mr. Hennessy,
May 28, 2021
Enclosed please find information supporting an application for a discharge system for a 3-
Bedroom Single -Family Residence (SFR) located in Forsyth County, North Carolina. The
proposed system will replace a failing sub -surface system that currently serves the residence. The
site has been deemed unsuitable for ground absorption sewage treatment systems by the
Forsyth County Department of Environmental Services due to unsuitable soil conditions and
insufficient space.
The proposed system is to be sized for 3 bedrooms (360 gallons per day) and has been designed
to convey all wastewater from the SFR, including greywater, to the new septic tank. The site's
existing septic tank is to be abandoned. This application is being submitted with the intent to
have coverage under the NCG55 General Permit. Coverage under this permit is sought to
replace a failed sub -surface system.
The following information is included with this letter:
Notice of Intent (NCG550000). Attachment A.
$60 check payable to North Carolina DEQ.
Documentation from Forsyth County Health Department. Attachment B.
Letter requesting coverage under the General Permit. Attachment C.
Letter requesting Authorization to Construct. Attachment D.
Soils Evaluation report by Jeff Vaughn, L.S.S. of AWT, Inc. Attachment E.
Correspondence from USGS. Attachment F.
Flow Path to "Blue Line" Water Feature. Attachment G.
Information on connection to Regional Sewer System. Attachment H.
Engineering Alternatives Analysis (EAA). Attachment I.
Local Government Review Forms. Attachment J.
Plans and Specifications for the proposed system. Attachment K.

The proposed discharge point is in an un-named tributary of Mill Creek, located along
Beech Forest Road. The discharge system will utilize the following components:
New Septic Tank with Effluent Filter
AdvanTex AX-20 RT Pod
Re -circulation Pump Chamber (Integrate into AdvanTex Pod System)
UV Disinfection
Discharge Point with Rip -Rap
Flow Path to "Blue Line" Water Feature
The discharge point is an un-named tributary of Mill Creek that is on the applicant's
property and ultimate destination is Mill Creek. A map showing the path from the
discharge point to the first "blue -line" stream, as shown on the NC DEQ Stream
Classification Map, can be seen in Attachment G. The lat/long information presented
below is the approximate location of the confluence of the unnamed tributary with Mill
Creek.
Receiving Stream Mill Creek
Stream Class WS-IV
Notice of Intent
As part of the Notice of Intent, the feasibility of alternatives to discharging must be
addressed. The following alternatives are to be evaluated:
Connection to a regional or municipal sewer collection system.
Letter from the local or county health department describing the suitability
or non -suitability of the site for all types of wastewater ground adsorption
and innovative non -discharge systems, as well as documenting the repair
potential of the failed system.
Investigate land application such as spray irrigation or drip irrigation.
Connection to a Regional or Municipal Sewer Collection System
Connection to a sewer collection system will likely not be available. Correspondence
from the City of Lewisville, Forsyth County Water and Sewer, and City of Winston
Salem CityLink has not been received (after repeated requests). Per our own
investigation, we believe that the nearest sewer to the property is located in Lewisville,
NC. That would indicate that the closest sewer system to the subject property is in excess
of 2 miles from the applicant's property. At an estimated cost of $100/ft, the cost to
extend the sewer line would be $1,056,000 (plus engineering and tap fees).

Letter from the local or county health department describing the suitability or non -
suitability of the site for all types of wastewater ground adsorption and innovative
non -discharge systems. Document the repair potential of the failed system.
The Forsyth County Health Department indicated that the site is unsuitable for
installation of a ground absorption septic system in letter dated March 1, 2021.
(Attachment B). The letter indicated that an improvement permit cannot be issued due to
unsuitable soils.
Investigate Land Application such as spray irrigation or drip irrigation.
Per the soil evaluation by Chris McGee, L.S.S. of Agri -Waste Technology, Inc., the site
does not have adequate space and suitable soil to accommodate a non -discharge surface
spray or drip wastewater system (Attachment E). The report indicated the only repair
option is a discharge system.
7Q10 Flow Estimate
The United States Geological Survey (USGS) was contacted to determine the 7Q10 and
30Q2 flow estimates for the proposed wastewater discharge point. The proposed
discharge point is in an un-named tributary of Mill Creek. The analysis from USGS
indicates the 7Q10 discharge for the point in question is likely zero, but the 30Q2 for the
point in question likely has positive flow (Attachment F).
Engineering Alternatives Analysis
An Engineering Alternatives Analysis (EAA) has been completed for this site and is
included as Attachment H. The completed EAA demonstrates that a wastewater
treatment system permitted under the NCG550000 General Discharge Permit is the only
feasible option for this site. We have exhausted all other options for this site as follows:
a.) connection to a municipal or regional sewer collection system
- Not feasible due to costs (at the present time).
b.) subsurface disposal
- Inadequate soil for a subsurface absorption system.
c.) single-family residence wastewater irrigation (drip and spray)
- Inadequate soil and not feasible due to fill soil costs for a
non -discharge ground absorption system.
d.) reclaimed -water systems
- Inadequate soil and not feasible due to fill soil costs for a
reclaimed water system. No reasonable ability to operate
as a bulk distributor of reclaimed water.
e.) Any viable combination of the above
- There are no viable combinations of the above due to soil
and cost limitations.
Local Government Review Forms
As part of the EAA, Local Government Review Forms were sent to Forsyth County and
the Town of Lewisville. A copy of the form submittals is included as Attachment I. To
date, the completed forms have not been received.

Plans and Specifications
Plans and Specifications for the proposed system are included as Attachment J.
I appreciate your time and efforts in reviewing this application. If you have any
questions or comments, please feel free to contact me at 919-859-0669.

The Environmental Health Division, Forsyth County Health Department, evaluated the above -
referenced property on February24, 2021 at the site designated on the plat/site plan that accompanied your
application for a Repair Permit. The evaluation was performed in accordance with North Carolina General
Statute 130A-333 and related statutes, the NC "Laws and Rules for Sewage Treatment and Disposal
Systems," Title 15A, Subchapter 18A, Rule .1900, North Carolina Administrative Code, and related rules.
Based on the criteria set out in "Laws and Rules for Sewage Treatment and Disposal Systems," Title
15A, Subchapter 18A, North Carolina Administrative Code, Rules .1940 through .1948, the results of the
evaluation indicate that the site is UNSUITABLE for a ground absorption sewage system. Therefore, your
request for a Repair permit is DENIED. The site is unsuitable based on the following:
Unsuitable topography and/or landscape position (Rule .1940)
J Unsuitable soil characteristics (structure or clay mineralogy) (Rule .1941)
J Unsuitable soil wetness condition (Rule .1942)
J Unsuitable soil depth (Rule .1943)
✓ Presence of restrictive horizon (Rule .1944)
✓ insufficient space for septic system and repair area (Rule ,1945)
✓ Unsuitable for meeting required setbacks (Rule .1950)
Other (Rule .1946)
The home is currently served by an onsite wastewater system that was installed in 1978, the system is
currently malfunctioning. The additional property adjacent to the home owned by the homeowner was
evaluated as well to ensure that no option for an offsite wastewater system could be installed there as well.
The site evaluation included consideration of possible site modifications and modified, innovative or alternative
systems. However, the health department has determined that none of the above options will overcome the
limitations of this site.
Possible options include the following:
• obtaining a discharge permit from the NC Department of Environmental Quality
obtaining a pump and haul permit

For the reasons set out above,�the proposed repair septic area is currently classified UNSUITABLE, and a
CA shall not be issued for tl'iis site in accordance with Rule .1948 (c).
However, the site classified as UNSUITABLE may be classified as PROVISIONALLY SUITABLE if written
documentation is provided that meets the requirements of Rule .1948 (d), A copy of this rule is enclosed. You

15A NCAC 18A .1948 SITE CLASSIFICATION
(a) Sites classified as SUITABLE may be utilized for a ground absorption sewage treatment and disposal
system consistent with these Rules. A suitable classification generally indicates soil and site conditions
favorable for the operation of a ground absorption sewage treatment and disposal system or have slight
limitations that are readily overcome by proper design and installation.
(b) Sites classified as PROVISIONALLY SUITABLE may be utilized for a ground absorption sewage
treatment and disposal system consistent with these Rules but have moderate limitations. Sites
classified Provisionally Suitable require some modifications and careful planning, design, and
installation in order for a ground absorption sewage treatment and disposal system to function
satisfactorily.
(c) Sites classified UNSUITABLE have severe limitations for the installation and use of a properly
functioning ground absorption sewage treatment and disposal system. An improvement permit shall
not be issued for a site which is classified as UNSUITABLE. However, where a site is UNSUITABLE, it
may be reclassified PROVISIONALLY SUITABLE if a special investigation indicates that a modified or
alternative system can be installed in accordance with Rules .1956 or .1957 of this Section.

MEMORANDUM
TO: Mr. Richard Clayton
FROM: Jeff Vaughan, NC L.S.S.
SUBJECT: Soils Evaluation for 7825 Beech Forest Road
Lewisville, NC (Forsyth County)
A soils evaluation was conducted for the property located at 7825 Beech Forest Road, Lewisville,
NC (Forsyth County). The evaluation was conducted by Trevor Hackney for Jeff Vaughan, NC
L.S.S. of AWT on April 16, 2021. A conventional gravity septic system is located on the property
and currently serves the 3-bedroom single-family residence located on the site. The septic system
is located behind the residence. The system was found to be backing up and malfunctioning during
a recent septic system inspection (performed by another septic system inspector/contractor) as part
of a real estate transaction.
The current land use, i.e. house footprint, outbuilding footprint, driveway, pavement, landscaping,
etc., and setbacks required for the buildings, property line, and a current drainage area impedes the
potential to permit a subsurface or surface application wastewater system. Additionally, the
property predominantly contains the Codorus Loam soil type, which is typically poorly suited for
subsurface septic systems due to wetness. The in -field investigation indicated that the soil was
unsuitable for septic systems due to the presence of wetness indications and/or fill soil within 12
inches of the soil surface. Therefore, the site is unsuitable for septic systems.
The subject property is unsuitable for subsurface and surface application wastewater systems due
to inadequate space and unsuitable soils. Therefore, the property does not comply with the
requirements of 15A NCAC 18A Section .1900 — Sewage Treatment and Disposal Systems -or-
15A NCAC 02T Section .0600 — SFR Wastewater Irrigation Systems. The site is a likely candidate
for a surface water discharge system.
Please contact us with any questions, concerns, or comments.

USGS response to DWR USGS Low Flows request # 2021-121 (dated 2021/04/13) for
UT Mill Creek Forsyth County...RE: [EXTERNAL] Low -flow request approval
Weaver, John C <[e-mail]>

<[e-mail]>
Ms. Davidson,
In response to your inquiry about the low -flow characteristics (7Q10, 30Q2) for a location on an
unnamed tributary to Mill Creek (adjacent Beech Forest Road) at Grapewood (vicinity of Lewisville) in
central western Forsyth County, the following information is provided:
A check of the low -flow files here at the USGS South Atlantic Water Science Center (Raleigh office)
does not indicate a previous low -flow determination for the point of interest, identified by the
lat/long coordinates (36.11732, -80.42784) provided via email dated 04/13/2021 from the DWR
USGS Low Flow portal following your request submission
No USGS discharge records are likewise known to exist for the point of interest.
In the absence of site -specific discharge records sufficient for a low -flow analysis, estimates of low -
flow characteristics at ungaged locations are determined by assessing a range in the low -flow yields
(expressed as flow per square mile drainage area, or cfsm) at nearby sites where estimates have
previously been determined.
For the record: The point of interest is located approximately 2,200 feet downstream from the dam
for a small impoundment on this stream. The estimated low -flow characteristics provided below do
not account for the presence of this upstream impoundment, but the estimates reflect "natural flow"
conditions as though the impoundment was nonexistent.
A basin delineation completed using the online USGS StreamStats application for North Carolina
(https://streamstats.usgs.gov/ss/) indicates the drainage area for the point of interest (StreamStats
adjusted coordinates 36.11732, -80.42785 NAD83) is 0.21 sqmi, which confirms the drainage area
submitted as part of the request information.
For streams in central western Forsyth County, low -flow characteristics published by the USGS are
provided in the following reports:
(1) The first is a statewide report completed in the early 1990's. It is USGS Water -Supply Paper 2403,
"Low -flow characteristics of streams in North Carolina" (Giese and Mason, 1993). An online version
of the report is available at http://pubs.usgs.gov/wsp/2403/report.pdf. The report provides the low -
flow characteristics (based on data through 1988) via regional relations and at -site values for sites
with drainage basins between 1 and 400 sqmi and not considered or known to be affected by
regulation and/or diversions.
(2) The second is a statewide report published in March 2015. It is USGS Scientific Investigations
1 of 4 4/28/2021, 10:03 AM

Firefox https://outlook.office.com/mail/inbox/id/AAQkAGE5ODAwZGVjLTg...
Report 2015-5001, "Low -flow characteristics and flow -duration statistics for selected USGS
continuous -record streamgaging stations in North Carolina through 2012" (Weaver, 2015). The
report is available online at http://pubs.usgs.gov/sir/2015/5001/. The report provides updated low -
flow characteristics and flow -duration statistics for 266 active (as of 2012 water year) and
discontinued streamgages across the state where a minimum of 10 climatic years discharge records
were available for flow analyses.
Low -flow characteristics estimated for point of interest:
Inspection of the above reports indicates the presence of six (6) nearby selected USGS partial -record
sites (5) and continuous -record streamgages (1) in the general vicinity of the point of interest where
low -flow characteristics were published. Among these 6 sites, the low -flow discharge yields for the
indicated flow statistics are as follows:
Annual 7Q10 low -flow yields ==> from 0.08 to 0.15 cfsm (both average and median about 0.12 cfsm)
Annual 30Q2 low -flow yields ==> from 0.3 to 0.34 cfsm (average about 0.32 cfsm, median about 0.33
cfsm)
Winter 7Q10 low -flow yields ==> from 0.25 to 0.33 cfsm (average about 0.29 cfsm, median about
0.28 cfsm)
Annual 7Q2 low -flow yields ==> from 0.23 to 0.27 cfsm (average about 0.25 cfsm, median about 0.26
cfsm)
Average annual discharge yields ==> from 0.9 to 1 cfsm (average about 0.99 cfsm, median about 1
cfsm)
Application of the above range in yields to the drainage area (0.21 sqmi) for the point of interest
results in the following estimated low -flow discharges:
Annual 7Q10 low -flow discharges ==> from 0.017 to 0.032 cfs (both average and median about 0.025 cfs)
e rounded down to zero flow
Annual 30Q2 low -flow discharges ==> from 0.063 to 0.071 cfs (average about 0.067 cfs, median about
0.069 cfs) e rounded to 0.07 cfs
Winter 7Q10 low -flow discharges ==> from 0.053 to 0.069 cfs (average about 0.061 cfs, median about
0.059 cfs) e rounded to 0.06 cfs
Annual 7Q2 low -flow discharges ==> from 0.048 to 0.057 cfs (average about 0.053 cfs, median about
0.055 cfs) e rounded to 0.05 cfs
Average annual discharge discharges ==> from 0.19 to 0.21 cfs (both average and median about 0.21 cfs)
Please note:
(1) The estimated flows are provided in units of cubic feet per second (cfs).
(2) The low -flow yields provided above are rounded to 2 significant figures. Estimated low -flow
discharges less than 1 cfs are rounded to 2 significant figures. If between 1 and 100 cfs, then
rounded to 1 decimal place; if greater than 100, then rounded to the nearest whole number (zero
decimal places).
(3) The information provided in this message is based on a preliminary assessment and considered
provisional, subject to revision pending collection of future data and further analyses.

Engineering Alternatives Analysis (EAA) Guidance Document
North Carolina Division of Water Resources
STEP 1. Determine if the proposed discharge will be allowed
Non -municipal applicants.
Due to staff constraints, the NPDES Unit cannot prepare speculative limits for non -municipal applicants.
Thus, it is your responsibility to make your own determination as to whether the proposed discharge might be
allowed by the Division, by evaluating the water quality factors listed above. It is highly recommended that
you discuss the proposed discharge with the applicable DWR Regional Office and/or NPDES Unit staff, who
may be able to provide input on the likelihood of a new/expanding discharge. As a first step, you must
obtain streamflow estimates for the proposed discharge location to ensure that the receiving stream is not
subject to zero flow restrictions. Low flow data (specifically, drainage area, the summer and winter 7Q10,
average flow and 30Q2 flow statistics) can be obtained for a nominal fee from the U.S. Geological Survey in
Raleigh at 919-571-4000. The low flow data must be submitted with the EAA, and will be used by the permit
writer to develop permit limits. You must also verify that the proposed action (i.e., construction of a
wastewater treatment plant and its appurtenances) is consistent with local zoning and/or subdivision
ordinances. You will need to request the local government(s) to complete a Local Government Review Form
(Attachment A), and include the signed and notarized form with your NPDES application package.
Response: The United States Geological Survey (USGS) was contacted to determine the 7Q10 and 30Q2 flow estimates for
the downstream tributary of the proposed wastewater discharge point. The proposed discharge point is in an un-
named tributary of Mill Creek. The analysis from USGS indicates the 7Q10 discharge for the point in question is
zero and the 30Q2 for the discharge point is 0.07 cfs (Attachment F of application package). Because this
positive flow, the discharge will be considered on a case -by -case basis.
All applicants.
If you conclude that the proposed discharge will pass the "allowable discharge" criteria, then begin the EAA
preparation by summarizing the following general information about the proposed project:
• Provide a description of the proposed project. If the project will be constructed in phases, provide a
schedule for constructing each additional phase, and provide the projected flow per phase (see STEP 2).
Response: A wastewater discharge system is to be constructed for a 3-Bedroom Single Family Residence (SFR) located in
Forsyth County, North Carolina. The proposed system will replace a failing sub -surface system that currently
serves the residence. The proposed discharge point is in an un-named tributary of Mills Creek located on the
applicant's property. The proposed treatment system will utilize the following components:
Septic Tank with Effluent Filter (existing tank to be abandoned)
AdvanTex AX-20 RT Pod
Recirculation Pump Chamber (Integrated into AdvanTex Pod System)
UV Disinfection
Discharge Point with Rip -Rap
Construction of the proposed system will occur in a single phase with an anticipated completion time of
approximately 2 weeks after the start of construction activity.

STEP 2. Provide reasonable projections for population and flow
Residential Population Projections.
Facilities requesting an NPDES discharge permit for new or expanding domestic wastewater discharges
must document the population to be served within the service area over a 20-year planning period. The NC
State Demographics unit provides population data for each county and municipality and can be accessed on
the Internet at http://www.demog.state.nc.us. If 20-year population projections for specific areas are not
available, a linear extrapolation of population trends from the past decade should be used. Any deviation
from a linear projection method must be clearly justified. If population projections include future
annexations, include a proposed annexation schedule as well as any annexation requirements that must be
met.
Response: Because the wastewater treatment system is designed for a single-family residence, the population to be served
will be limited by the number of bedrooms at the individual residence. The existing house contains 3 bedrooms.
For the 20-year planning period, the system will be designed for a 3-bedroom residence with a flow of 360
gallons per day. At 2 people per bedroom, the system will be designed to serve 6 residents.
STEP 3. Evaluate technologically feasible alternatives
Alternative A. Connection to an Existing Wastewater Treatment System.
You must evaluate the feasibility of connecting to an existing wastewater treatment system served by a
municipality or other entity holding a valid NPDES or Non -Discharge Permit. All connection options
should include an evaluation of a gravity line and/or force main with pump station(s).
1. Existing Sewerage System:
(a) Identify whether there are existing sewer lines within a five -mile radius, or consider a greater
radius if cost effective for the project size.
Response: Connection to a sewer collection system is likely not feasible for this facility. Correspondence was not returned
about sewer connection, but per our evaluation we the closest sewer system is likely located in Lewisville, NC
which is in excess of 2 miles away from the applicant's property. For reference, if an installation cost of $100/ft
EAA Guidance Document Revision: April 2014
Page 2 of 8

of installed sewer line was assumed, the cost to connect this property to the sewer line would exceed $1,056,000.
Additional costs including the cost of the pump station, potential "tap" or sewer capital fees, road repair costs,
frontage fees and fees for right of way permits would also be incurred by the homeowner.
(b) Provide a preliminary indication of flow acceptance from existing municipal or private
WWTPs under consideration for connection. If a municipal or private WWTP cannot accept
the wastewater, include a letter documenting such and consider this alternative
technologically infeasible.
Response: N/A No sewerage available
(c) If an existing sewerage system will accept the wastewater, evaluate the
piping/pumps/resources necessary to connect to the existing wastewater treatment plant.
Attach a topographic map or a site drawing showing the physical route of this alternative.
Conduct a Present Value Cost Analysis per STEP 4.
Response: N/A No sewerage available
2. Planned Sewerage System: Determine if a regional sewerage system within a five mile radius is
projected to be available within the next five years to receive waste from the project site. If
applicable, determine availability date and flow acceptance projection from appropriate
authority.
Response: No plans to extend their coverage area toward the applicant are known of at this time.
Alternative B. Land Application.
Land application disposal alternatives include individual/community onsite subsurface systems, drip
irrigation, and spray irrigation.
1. Provide an estimate of the best case hydraulic loading rate based on County Soil Surveys or from
a soil evaluation performed by a soil scientist. Include calculations showing the hydraulic
loading rate and the total area of land needed for the land disposal system, including buffers.
Response: The Forsyth County Department of Public Health indicated that the site is unsuitable for installation of a ground
absorption septic system in a letter dated March 1, 2021 (Attachment B of application package). The letter
indicated that a permit cannot be issued due to unsuitable soil wetness conditions, unsuitable soil characteristics,
unsuitable soil depth, presence of restrictive horizon, and insufficient space.
Per the soil evaluation by Christopher McGee of Agri -Waste Technology, Inc., the site does not have suitable
soil or space to accommodate a ground absorption or surface drip or surface spray wastewater system
(Attachment E of application package).
Regardless of the fact that a subsurface ground absorption cannot be designed or permitted for this site, the
potential size of a subsurface system has been estimated. According to the web soil survey, the site is classified
as a Codorus Loam soil CoA). This silty loam soil frequently floods and would be very restrictive for
wastewater systems. For a subsurface system in this soil, a drip system with pretreatment would be required.
These soils would have a long-term acceptance rate (LTAR) ranging from 0.05-0.15 gpd/sq.ft., with a typical
rate of 0.1 gpd/sq.ft. Subsurface systems also require the drainline to be installed with the contour so that each
drainline is at a constant elevation. This results in a "fanning" of the drainline and requires additional space in
order to install the required amount of drainline. The sizing calculation is summarized in the table below:
EAA Guidance Document Revision: April 2014
Page 3 of 8

Subsurface Dripfield Design Alternative
# Bedrooms 3
Daily Flow 360 gpd
LTAR 0.1 gpd/sqft
= 120gpd * #bedrooms
Minimum Area Required (Nominal) 3,600 sqft = Daily Row /LTAR
Estimation for Topographical Variation 1,200 sqft
Estimated Area Required (Actual) 4,800 sqft
Approximate Area Available 25,065 sqft
The current property's land available for the system is 25,065 sqft, due to setbacks and existing site conditions.
A schematic of this area is shown in Appendix A of the EAA. The land needed for a subsurface dripfield
design is a minimum of 4,800 sq. ft., so there is sufficient space for this type of system at the residence.
Although there may be sufficient space, due to limitations caused by the soil characteristics and conditions,
this property is not suitable for a subsurface system.
The potential size of a non -discharge surface application system has also been estimated. According to the
web soil survey, the site is classified as a Codorus loam soil. For a surface system in this soil, the SFR loading
rate group is likely restricted to a maximum annual loading of 19.5 in/year. The sizing calculation for a non -
discharge surface system is summarized in the table below:
Non -Discharge Surface Design Alternative
# Bedrooms 3
Daily Flow 360 gpd
Surface Loading Rate 19.5 iniyear
Minimum Area Required (Nominal)
Approximate Area Available
10,810 sqft
0 sqft
rOgp # d-corns
The current property's land available for a surface drip or spray system is 0 sqft, due to setbacks and existing site
conditions. The major limiting factors that prevent this type of system are the 100' stream setback, the 50'
property setback, and the location of the SFR as well as the 15' foundation setback. The potential for waving
property setbacks has been considered and would allow for 6,952 sqft. A schematic of this area is shown in
Appendix A. The land needed for a non -discharge application system is estimated at 10,810 sq. ft., so there is
insufficient space for this type of system at the residence.
2. Assess the availability of land. If insufficient land is available onsite, assume that the necessary
land can be purchased and estimate the land purchase cost based on local real estate prices.
Alternatively, provide documentation to demonstrate that insufficient land is available for sale in
the project area (include letters from adjacent property owners indicating no interest in selling
property).
Response: Because insufficient land is available onsite (due to inadequate soil and inadequate space), offsite land was
reviewed. The table below lists neighboring properties and the value of the land as listed by the Wake County
GIS website. The values listed in the table do not reflect the value of the single-family residences. The soil
types listed for these properties are Codorus series (Co), Poplar series (Po), and Tomlin series (Tm). These
sites, like the applicant's site, will be very restrictive for wastewater systems. Much of the listed southern and
western parcels are restricted for septic application by topography and unnamed tributaries of Mill Creek.

3. Provide a description of the wastewater treatment system and the non -discharge application
system. Include a site plan showing the proposed layout, the application area, any existing
structures, proposed structures, and other uses within the site.
Response: A typical subsurface drip system or a non -discharge surface spray or surface drip system with pretreatment
considers the following components:
- Septic Tank with Effluent Filter
- Recirculation Tank (Integrated in AX20-RT unit)
- AdvanTex Treatment Pod (AX20-RT unit)
- Pump Tank (potentially integrated in AX20-RT unit)
- UV Disinfection (Integrated in AX20-RT unit)
- Headworks Box
- Control Panel
- Disposal Field (drip or spray) with addition of fill soil
Note: The proposed discharge system does not consider the pump tank, headworks box or disposal field.
Site drawings of these alternative systems showing the available application area are included as Appendix A
of the EAA. Due to the cost requirements of a drip or spray system and the lack of sufficient soil, there is no
ability to consider any of these systems on this property.
4. Explain the proposed reuse plan if reclaimed water will be used by a third party.
Response: There is no reuse plan being considered either on -site or by a third party. The residential plumbing
infrastructure does not allow for reuse in the proposed residence. It is not feasible to consider using
reclaimed water on the site or becoming a bulk distributor of reclaimed water. The table below summarizes
the amount of reclaimed water that could be beneficially used on site. As shown in Appendix A, there is
sufficient area to utilize the daily flow of reclaimed water. Although there may be sufficient space, due to
limitations caused by the soil characteristics and conditions, this property is not suitable for on -site
utilization of reclaimed water. Regardless of the fact that the soil at this site is not suitable for this system,
installing this system would not be feasible due to costs.

5. Conduct a Present Value Cost Analysis per STEP 4. For the reclaimed water system include the
potential revenue generated by selling the water.
Response: A Present Value Cost Analysis is included as Appendix B of the EAA. An analysis was performed for a
sub -surface drip system, a non -discharge surface application system, and a reclaimed water system. A
summary of the analysis is included in STEP 4.
6. Provide all calculations, documentation and maps as necessary to support assumptions and
conclusions.
Response: Calculations performed to evaluate land application alternatives are shown above in Alternative B, Points 1
and 4.
7. Note: The design of land application systems must meet the treatment and design requirements
specified in 15A NCAC 2T .0500 or 15A NCAC 18A.1900.
Response: The treatment systems specified above in Step B would meet the treatment standards required by these rules
as they pertain to single family residences. However, due to the restrictions listed above, no land -based
systems can be considered.
8. Note: Proposed discharges from groundwater remediation systems must evaluate the potential
for an infiltration gallery treatment alternative.
Response: N/A
Alternative C. Wastewater Reuse.
You must evaluate reusing all or a portion of the wastewater generated. Some municipalities are currently
reusing wastewater within the confines of their WWTP property for irrigation, toilet flushing, backwashing,
etc., while other municipalities have established progressive reuse programs for residential irrigation. Reuse
applications might include golf course irrigation, crop irrigation (e.g., hardwood or pine plantation,
grasses), athletic field irrigation, landscape uses, and commercial/industrial uses. Some of these reuse
applications will be evaluated under Alternative B, Land Application. The design of reclaimed water
systems must meet the treatment and design requirements specified in 15A NCAC 2U.
Response: All reuse applications for this project scale were evaluated under Alternative B, Point 4. Wastewater reuse
was determined to be infeasible for this project.
Alternative D. Direct Discharge to Surface Waters.
1. No new or expanding (additional) discharge of oxygen -consuming waste will be allowed to
surface waters of North Carolina if both the summer 7Q10 and 30Q2 streamflows are estimated
to be zero, in accordance with 15A NCAC 2B.0206(d). Private applicants must contact the USGS
in Raleigh at 919-571-4000 and obtain (generally for a nominal fee), the receiving streamflow data
(s7Q10, 30Q2, annual average streamflow) at the proposed discharge location. This information
must be included in the EAA, and will be used to develop permit limits.
Response: Because the 30Q2 evaluation shows positive flow, the discharge should be considered an option.
EAA Guidance Document Revision: April 2014
Page 6of8

2. All direct discharge systems of oxygen -consuming wastes should be evaluated both with tertiary
filtration [BOD5= 5 mg/1, NH3-N= 1 mg/1] and without, and assuming a weekly sampling
regime.
Response: Tertiary filtration is not required under the general permit, as the general permit requirements (monthly
average) are BOD5 = 30 mg/1 and Total Suspended Solids = 30 mg/1. However, based on actual sample
results from similar treatment systems (other facilities using the same technology) in many cases, a BOD5 of
5 mg/1 and NH3-N of 1 mg/1 can be met. While weekly sampling of the treated effluent would confirm the
treatment results on a regular basis, the additional cost associated with the collection and testing of the
effluent would not be feasible for the homeowner.
3. Provide a description of the proposed wastewater treatment facilities, including a schematic
diagram of the major components and a site plan of the treatment facility with outfall line(s).
Response: Plans and schematic drawings can be found in Attachment K (of application package).
4. Provide documentation of the availability of required land and/or easement agreements.
Response: N/A
5. Conduct a Present Value Cost Analysis per STEP 4.
Response: A Present Value Cost Analysis for the discharge system is included in Appendix B. A summary of the
analysis is included in STEP 4.
6. Note: All direct discharge treatment systems must comply with Reliability Requirements
specified in 15A NCAC 2H.0124.
Response: The system serves a private facility that is served by city water and does not have elevated water storage
tanks. In the event of a power outage, water may still be available to the residence. There is storage
available in the system to hold some waste from the house until power is restored to the system.
Alternative E. Combination of Alternatives.
You should evaluate the possibility of a combination of wastewater alternatives that would minimize or
eliminate a direct discharge alternative. For example, consider whether the facility can operate a land
application system during the dry season when streamflows are at their lowest and provide less dilution, and
operate an NPDES discharge system during the wet season when soils may not be as amenable to land
application and the receiving stream provides its greatest dilution.
Response: A non -discharge alternative is not feasible due to the space and soil constraints listed in Alternative B. The
presence or absence of a seasonal high water table will not relieve the other constraints.
EAA Guidance Document Revision: April 2014
Page 7 of 8

STEP 4. Evaluate economic feasibility of alternatives
PVCA Summary Table.
The EAA must include a Summary Cost Table, which summarizes present worth costs developed for all
technologically feasible wastewater alternatives. The summary should include a breakdown of capital costs
and recurring costs. In some situations, the Division may require the applicant to refine cost estimates for
some alternatives, or possibly collect actual soil data to better characterize the land application alternative.
Ultimately, the final determination on cost effectiveness is made by the Division with consideration of
monetary costs as well as potential environmental impacts.
Response: The following table presents the cost analysis for several types of wastewater systems. Given the
information presented above, the only technologically feasible alternative is the Discharge System. The
"Install Cost" includes the estimated cost to design and install the specific type of system. The installation
cost does not include the cost of fill soil that would likely need be added, at the direction of a L.S.S., to
maintain suitable soil depths within a drainfield. The cost to relocate existing utilities (gas line and water
line), which is required to install a septic/irrigation field in the front yard, is not included. The "Present
Value of Costs" is based on a discount factor of 1.2%.

RE: Local Government Review Form
Application for Discharge System — Clayton Property
7825 Beech Forest Road, Lewisville, NC 27023
Dear Mr. Perkins,
April 19, 2021
Enclosed please find a Local Government Review Form required for a Certificate of
Coverage application supporting a proposed wastewater treatment system (system). The
proposed system will be permitted under the NCG550000 General Discharge Permit for
Single Family Residences (SFRs). The proposed system will serve an existing 3-
Bedroom SFR located in Forsyth County, North Carolina. The proposed system will
replace a failed sub -surface system that currently serves the SFR.
The site has been deemed unsuitable for ground absorption sewage treatment systems by
the Forsyth County Department of Environmental Services due to unsuitable soil
conditions and insufficient space. It is my opinion that a wastewater treatment system
covered by the General Discharge Permit is the only technologically and economically
feasible option for this residence.
Please complete the enclosed form for inclusion in the application for the proposed
system. This residence is located in Forsyth County, nearby the town of Lewisville.
Please note that this form is only meant to determine zoning/jurisdiction information for
the county and does not indicate your approval of the proposed system.
I appreciate your time and efforts in completing this form. If you have any questions or
comments, please feel free to contact me at 919-367-6310.
Best Regards,
Kevin Davidson, P.E.

Narrative Description
of
Discharge Treatment System
The Discharge System that has been designed considers the following components:
- Septic Tank
- AdvanTex AX20-RT Treatment Pod
- UV Disinfection
- Discharge Outlet
- Control Panel
Due to the advanced technology in this system, a Certified Operator should be contracted to
maintain this system.
Septic Tank
A new 1,250-gallon septic tank will be installed for this system. The septic tank will include an
effluent filter and risers. An Orenco 8" Biotube effluent filter will be installed in the outlet end of
the septic tank. New access risers will be installed on both the inlet and outlet ends of the septic
tank. To facilitate the installation of the access risers, riser adapters will be cast into the tank top
during construction. All wastewater from the single-family residence, including greywater, will be
routed into the septic tank. Waste that exits the septic tank will flow into the AdvanTex AX20-RT
Treatment Pod.
AdvanTex AX20-RT Treatment Pod
The treatment component of the system is an AdvanTex AX20-RT treatment pod. The pod is an
integrated unit that combines recirculation, treatment, and discharge modules into a single, sealed
unit. Liquid from the septic tank will flow via gravity to the inlet of the treatment pod and into the
recirculation tank portion of the AX-RT unit. Liquid from the recirculation tank will be periodically
applied across the filter fabric. Wastewater will be sprayed over the textile sheets. The wastewater
percolates down through the textile sheets and is distributed between the recirculation chamber and
discharge chamber by means of the tank baffle. The treated wastewater will be pumped from the
AX-RT unit to the discharge outlet. Prior to exiting the AX-RT unit, effluent passes through the UV
disinfection system.
The recirculation pump is controlled by a system of 3 floats that operate the recirculation pump in a
Timed Dose arrangement. Float 1 (lowest elevation) is a Redundant Off float. Float 2 is a Peak
Enable Float and Float 3 acts as a High Water Alarm. Under normal operation the Redundant Off
float will be engaged thereby activating the timer in the control panel. At the pre-set interval, the
pump will engage and distribute effluent over the textile fabric ("on" cycle). Following this period,
the pump will turn off and rest for a designated time ("off" cycle)". During periods of high water in
the recirculation portion of the tank, the Peak Enable float will engage and reduce the pre-set "off'
time and thereby send increased flow across the fabric. If the water level in the recirculation tank
continues to rise for a pre-set time period, the High Water Alarm will activate.
1

To prevent groundwater from affecting the pod, the pod will be installed on a bed of gravel. Anti -
flotation measures or a concrete ring installed around the mid -flange will be installed to provide
extra ballast to prevent the flotation of the pod during high water table conditions.
UV Disinfection
Disinfection for the system will be accomplished using a UV system. The UV light should operate
for approximately one year prior to needing to be replaced. If the UV light burns out or loses
sufficient intensity (below a set threshold) an alarm will activate and disable the system pump. An
alarm light on the control panel will also illuminate. When the alarm is activated, the homeowner
should reduce water use (laundry, dishes, washing) until the system is operating properly. Treated
effluent can be sampled from the UV housing.
Discharge Outlet
The system discharges into a ditch on the north eastern part of the property. Riprap will be placed at
the discharge location to provide aeration of the water as it is discharged and also as erosion
protection. Vegetation and debris should be kept clear of the discharge location. A grate will be
installed on the discharge pipe to prevent animals and rodents from entering the discharge pipe.
Control Panel
One control panel will be installed with this wastewater system. This panel will control operation of
the re -circulation pump and UV system. If desired, this panel can be connected to a land -based
phone line that will notify the operator of system operation.

Technical Data Sheet AIM
PRTA ABS Tank Adapters
Applications
PRTA tank adapters are used to provide a structural, watertight method
of installing a 24-or 30-inch (600- or 750-mm) access riser over a tank
opening.
General
Orenco's PRTA tank adapters are molded plastic products and there-
fore have excellent part -quality and consistency. PRTA tank adapters
can be cast into a tank or fastened to the top of the tank with a bolt -
down kit. The bolt -down kit consists of either six or twelve (depending
on model) stainless steel concrete anchors and a roll of butyl tape.
The O.D. of the vertical flange matches the I.D. of Orenco's ribbed
risers, which provides a suitable joint to seal with MA320, ADH100,
SS115, or SS140 adhesive.

PVC Riser Installation
Installing PVC Access Risers onto Cast -In Orenco® Riser -Tank Adapters
Access risers provide access to septic tank openings, simplifying inspection and maintenance procedures. Access riser -to -tank connections
must be watertight for the proper functioning of an onsite septic system or effluent sewer system. Orenco strongly recommends watertightness
testing of all access riser -to -tank connections after installation.
Following are instruction sets for prepping and installing access risers, installing grommets, and selecting adhesives for riser installations.
Refer to the chart below to determine which instruction set to use.

7. Adhesive Selection and Quantities 7
Instruction Set 1: Riser Preparation
Step 1: Determine Riser Height
Determine how high the riser needs to be.
• The top of the riser should be about 3 inches (75 mm) above finished grade
after installation and backfilling — This allows 2 inches (50 mm) for tank
settling and 1 inch (25 mm) for ensuring drainage away from the riser.
Step 2: Cut Riser to Size (if Necessary)
If the riser needs to be cut to size, cut it with a circular saw or table saw.
• Always cut excess length from the bottom of the riser.
• For square, even cuts, a good fit, and a watertight joint between the riser
and the adapter, use an Orenco riser -cutting saw guide.
• To install risers less than 30 inches (760 mm) wide onto 500-gallon
(2000-L) Orenco FRP tanks, cut the riser so it fits into the tank and the
lowest rib rests on the tank's top, as shown.
Step 3: Dry Fit Riser to Adapter
Step 3a: Dry fit the riser to the adapter.
• Make sure riser penetrations are the right sizes and in the correct locations.
Step 3b: If the riser is higher than 3 inches (75 mm) above the estimated final
grade, cut it to size per the instructions in Step 2.
Step 3c: If the riser is too short, use an Orenco grade ring to extend it.

PVC Riser Installation
Instruction Set 2: Grommet Installation
Step 1: Mark Access Riser
Step 1a: Use the site plans or drawings to find out if riser penetrations are needed.
Step 1 b: Use the plans or drawing to mark the locations of the penetrations.
• If plans or drawings aren't available, use Drawing 1 b as a general guide
for locating riser penetrations.
Step 2: Drill Holes and Clean Access Riser
Step 2a: Drill holes for riser penetrations.
• If you have questions about where to locate various riser penetrations,
contact your Distributor for more information.
Using Orenco® RKHS Hole Saws ...
Cut the hole and grind the ribs down to make a flat, smooth surface for
installing the grommet.
• Make sure your hole saw is the correct size and your drill is at least 18 volts.
• Don't grind too deeply — about 1/16 inch (1.6 mm) is deep enough.
Using Standard Hole Saws ...
1: Use the correctly sized hole saw to cut a hole, centered on the mark.
2: Trim the riser ribs back 1 inch (25 mm) from around the hole.
• Use a grinder or cutting tool to notch the ribs through to the riser wall.
• Use a hammer and chisel to break off the notched rib sections.
• Use a grinder to make a flat, smooth surface around the hole.
Step 2b: Clean and deburr the hole and flat surface with a wire brush and
deburring knife or tool.
• Be careful not to enlarge the penetration.
Step 3: Install Grommet
Step 3a: Apply a bead of adhesive to the groove in the grommet's outer diameter.
• For adhesive recommendations, see Instruction Set 7.
Step 3b: Firmly press the grommet into the penetration.

Step 1c: Fill the tank with water to a level 2 inches (51 mm) into the riser.
Step 2: Test Watertightness an
Step 2a: Wait for the required time before inspecting the riser -to -tank
connections for leakage.
• Follow the tank manufacturer's recommendations (or applicable local regula-
tions) for wait times before inspecting the tank for leaks.
• Orenco recommends at least 30 minutes for its fiberglass tanks.
Step 2b: Check for any drop in the liquid level inside of the riser and any visible
leakage from the riser -to -tank connections.
• At the end of the test, there should be no drop in liquid level and no visible
leakage from seams, pinholes, or other imperfections.
• If leaks are found during the test, seal the leaks and repeat the test.
Step 2c: Once the riser -to -tank connections are proven watertight, remove the
plug(s) and drop the water level in the tank to just below the invert of the inlet or
outlet, whichever is lower,

large volume, and optional dividers make it useful for maintaining isolation
of high and low voltage wires where needed. It has four cord grips which
accommodate power cords for floats and pumps of 0.170 - 0.470 inches
(4.3 -11.9 mm) in diameter. Unused cord grips can be plugged watertight
with the supplied cord grip plugs. Each External Splice Box is provided with
a hole -cutting template to simplify installation on the riser and a 4-inch
(100-mm) diameter grommet for the riser penetration.
General
To specify the Orenco External Splice Box for your installation, require the
following:
• Watertight for prolonged submergence per UL listing (Type 6P)
• Attachment external to access riser to allow inspection with no need
to open the riser lid
• Volume of 100 in.3 (1639 cm3) for easy wiring access and to
accommodate multiple wiring configurations
• Bottom entry, so conduit or direct -bury cable always remains below
minimum burial depth
• Molded of UL (f1) rated plastic, resistant to cold and UV exposure,
suitable for external applications
• Optional divider plates available for isolating high and low voltage
wires from separate conduits or direct -bury cable

installation day, and you'll get fewer call-backs.
Key Point: Inspect your order for completeness and inspect each component for shipping damage. Check to be sure
instructions and items supplied comply with your state and local regulations. Carefully read and follow all instructions. Improper
installation may void warranties.
IMPORTANT: The backwash discharge from a salt -type water softener MUST NOT be plumbed into an AX-RT Treatment Unit
or the preceding septic tank. Failure to follow this instruction, or any other in this manual, will void the system's warranty.
Contact your AdvanTex Dealer if you have any questions about any household plumbing arrangements that may interfere with
the functioning of the system.
Note: All pipe diameters provided are U.S. nominal PVC pipe sizes. If you are using metric pipe, you may need adapters to
connect to the U.S. fittings supplied with AdvanTex Treatment Systems.
Septic Tanks Used in AX-RT Treatment Systems
Be sure that any septic tank used in an AX-RT Treatment System meets the following conditions:
• The tank must conform to an approved and authorized tank design for AdvanTex Systems, and it must meet all applicable regula-
tory requirements (no pour -in -place tanks, no homemade tanks, etc.). Call your local Dealer for specifics.
• The tank must be structurally sound.
• The tank must have at least 1000 gal. (3800 L) capacity for an AX20-RT, 1250 gal. (4730 L) for a 5-bedroom AX25-RT, and 1500
gal. (5680 L) for a 6-bedroom AX25-RT at the normal operating level (below the invert of the outlet).
• The tank must have an at -grade access with a watertight, securable and removable lid. If it doesn't, an at -grade access must be
installed onto the septic tank and be made watertight.
• The tank must be watertight and free of leaks.
• An Orenco effluent filter (model FTSO444-36V, FTW0444-36V, or FT0822-14B) must be installed in the septic tank.
Key Point: For existing septic tanks — the tank's depth of burial must allow for a minimum fall of 1/8 inch per foot (10 mm
per meter or 1 %) from the septic tank's invert of outlet to the AX-RT unit's invert of the inlet. If sufficient fall cannot be met, a
grade ring extension must be installed on the AX-RT or a pumping system will need to be installed in the septic tank to move
the filtered effluent to the AX-RT unit. (Contact your Dealer for assistance.)

Raw sewage enters the septic tank through its inlet tee. In the septic tank, the raw sewage separates into a scum layer, a sludge layer,
and a clear zone. Effluent from the clear zone passes through a Biotube® Effluent Filter and is discharged to the recirc/blend chamber
of the AX-RT unit. The effluent flows through the recirc transfer line to the recirc pumping system, which pumps filtered effluent to the
distribution manifold in the top of the unit. Effluent percolates down through the textile media and is divided — by means of a tank baffle
— between the recirc/blend chamber and the recirc/filtrate chamber inside of the unit.
The recirc pumping system's operation is controlled by a timer in the control panel. It allows the pump to dose the textile media for short
periods (usually 40-60 seconds), typically 72 times a day. These frequent "micro -doses," which optimize the treatment process, occur
throughout the day to maintain the proper biological environment.

This is a sample sketch of an AX-RT unit installed parallel
to the septic tank, with no antibuoyancy measures installed.
Distances and estimated fall from the septic tank's invert of
the outlet to the AX-RT unit's invert of the inlet are included.
AX-RT units require 18-24 inches (457-610 mm) space on
all four sides when installed in their own excavation.
Step 1: Review or Sketch Site Plans
Check the site plan for the specifics of your installation.
Key Point: If you're installing the AX-RT unit more than 20 ft (6 m)
from the septic tank, contact your Dealer for assistance.
Step la: Detailed Site Plan Provided
Make sure that the plan accurately reflects conditions at the site. If it
doesn't, contact the Designer before scheduling the installation.
Step 1 b: Plan Of Limited Detail Or No Site Plan Provided
If you are installing the AX-RT unit with a plan of limited detail or with no plan,
contact your local Dealer for assistance and then sketch a site plan that is
consistent with the Designer's specifications:
Key Points:
• Sketch the exact positions of the system components, pipes, electrical
conduits, etc. Account for current and likely future landscape features
in the sketch. (See Panel Installation, EIN-CP-GEN-1, for recommenda-
tions for installing control panels.)
• A minimum fall of 1B inch per foot (10 mm per meter or 1 %) is required
from the septic tank's invert of outlet to the AX-RT unit's invert of the inlet.
• The invert of the inlet on the AX-RT is 46 in. (1168 mm) up from the
base of the unit. The outlet is 24 in. (610 mm) down from the top of the
unit for pump dispersal or 41.5 in. (1054 mm) down for gravity dispersal.
• The bottom of the AX-RT lid must sit 2 inches (50 mm) above finished
grade when set and level. Standard unit height is 72 inches (1830 mm);
grade rings increase height by 6 or 12 inches (152 or 305 mm).
• If the AX-RT unit is installed in its own excavation, the unit requires
18-24 inches (457-610 mm) of space on all four sides.
• If the AX-RT unit is installed in tandem with the septic tank, a minimum of
2 ft (610 mm) separation distance is required between the unit and tank.
• If the AX-RT unit is being installed parallel to the septic tank, offset the
unit from the tank by 6 ft (1.8 m) if antibuoyancy measures are neces-
sary or 4 ft (1.2 m) if antibuoyancy measures are not necessary.
Step 2: Perform Excavation(s)
Step 2a: Before excavating, consider the necessary elevations, offsets, and
grade requirements for the AX-RT unit and (if needed) the septic tank.
Step 2b: Perform the excavation(s).
Key Points:
• Follow the manufacturer's recommendations for excavating the tank area.

Step 2: Perform Excavation(s), cont.
Step 2c: Make sure the bottom of the excavation is suitable for setting the
AX-RT unit and (if needed) the tank: stable, smooth, level, and free of debris,
rocks, and other sharp objects.
Key Points:
• Follow the manufacturer's instructions for bedding the tank.
• If the bottom of the excavation is uneven or rocky, lay a 4-in. (100-mm)
bed of sand or pea gravel and compact the material to create an even,
smooth surface.
Step 2d: If the bottom of the excavation is unstable, stabilize the bottom of
the excavation before continuing.
• For unstable base soil (peat, quicksand, muck, soft or highly expansive clay,
etc.), you may need to over -excavate the site depth and set a firm, 6-in.
(152-mm) compacted base of <_ %2- to 3/-in. (13- to 19-mm) aggregate
or pea gravel.
• For extremely unstable soil, you may need to pour a concrete layer to
stabilize the bottom of the excavation.
• If you have doubt about the soil's stability, consult a local civil or struc-
tural engineer.
Step 3: Set Septic Tank (If Needed)
Set the septic tank according to the manufacturer's instructions.
• Use Fiberglass Tank Burial instructions (NIN-TNK-1) to install 0renco's
500-gallon through 2000-gallon (2000-L through 7570-L) Fiberglass Tanks.
IMPORTANT: Take care to keep everyone clear of the excavation
when placing the tank.
Key Points:
• The tank has to be set at the correct depth to connect to the sewage inlet.
• A minimum fall of 1B inch per foot (10 mm per meter or 1 %) is required
from the septic tank's invert of outlet to the AX-RT unit's invert of the inlet.
Make sure the excavation is stable, smooth, level, and free
from debris, rocks, and sharp objects.

12 in. (300 mm)
18-24 in.
(460-600 mm)
When using Orenco fiberglass deadmen, be sure to place them
on a small lift of soil 12 inches (300 mm) from the bottom of
the AX-RT.
Step 4: Set AX-RT Unit
Step 4a: Attach proper lifting equipment to the lifting points on the AX-RT unit.
Step 4b: Carefully lift the unit and lower it into the correct position.
Step 4c: Remove the equipment when the unit is set and level in position.
IMPORTANT: Take care to keep everyone clear of the excavation
when placing the unit. Use a lifting device that will not damage
the unit or the unit's lid.
Key Points:
• A minimum fall of 1B inch per foot (10 mm per meter or 1 %) is required
from the septic tank's invert of outlet to the AX-RT unit's invert of the inlet.
• The bottom of the AX-RT lid must sit 2 inches (50 mm) above finished
grade when set and level.
• If the AX-RT unit is installed in its own excavation, the unit requires
18-24 inches (457-610 mm) of space on all four sides.
• If the AX-RT unit is installed in tandem with the septic tank, a minimum of
2 ft (610 mm) separation distance is required between the unit and tank.
• If the AX-RT unit is being installed parallel to the septic tank, offset the
unit from the tank by 6 ft (1.8 m) if antibuoyancy measures are neces-
sary or 4 ft (1.2 m) if antibuoyancy measures are not necessary.
Step 5: Install Antibuoyancy Deadmen (If Needed)
Determine if antibuoyancy deadmen are necessary for the installation.
0renco offers antibuoyancy hardware kits that can be used with Orenco
fiberglass deadmen or concrete deadmen.
• Deadmen are recommended for all installations.
• Deadmen are required if there is a potential for groundwater to be pres-
ent in the excavation at any time, or if surface runoff can fill the excava-
tion at any time, resulting in a "bathtub" effect.
afNote: This effect occurs in dense soils when water fills an excavation
during surface water runoff —usually during a heavy rain event —
before the disturbed soil in the excavation has had time to settle.
• If you are unsure whether to install antibuoyancy deadmen or not, con-
sult the system Designer or an engineer.
Step 5a: Installing Orenco Fiberglass Deadmen
Step 5a (i): Build up a 3- to 4-inch (75- to 100-mm) lift of soil on each
side of the unit for the deadmen to rest upon.
Step 5a (ii): Secure the deadmen along the length of the unit, on both
sides, with the antibuoyancy kit hardware. Then lower the unit into the hole.
Step 5a (iii): Place the deadmen at least 12 inches (300 mm) from the
bottom of the unit, and make sure they are level.

Installation Steps
Step 5: Install Antibuoyancy Deadmen (If Needed), cont.
Step 5b: Installing Concrete Deadmen
Notes:
• We recommend preparing concrete deadmen off site before installation.
• PVC forms for concrete deadmen can be made from 12-in. dia. x 4-ft
long (300-mm x 1200-mm long) PVC half -pipe or chamber material.
• Wooden forms for concrete deadmen can be built 12-in. wide x 6 in.
tall x 4 ft long (300-mm x 150-mm x 1200-mm).
Step 5b (i): Fill two forms halfway with concrete.
Step 5b (ii): Place two #4 reinforcing bars in each of the forms.
Step 5b (iii): Finish filling the forms.
Step 5b (iv): Sink eyebolts from the antibuoyancy hardware kit into the
concrete for attaching the deadmen later.
Step 5b (v): Let the concrete set completely before moving the deadmen.
Step 5b (vi): Use appropriate lifting gear to set the deadmen in place.
Step 5b (vii): Secure the deadmen along the length of the unit, on both
sides, with the antibuoyancy hardware kit and make sure they are level.
Step 6: Partially Backfill Excavation(s)
Partially backfill around the AX-RT unit and (if needed) the tank. Follow the
manufacturer's instructions for backfilling around the tank. Follow the steps
below to backfill around the AX-RT unit.
IMPORTANT: Bolt down the AX-RT lid before backfilling! Bolting
down the lid increases rigidity and helps prevent deformation.
Step 6a: Fill the AX-RT with 16 in. (410 mm) of water on both sides of the baffle.
Step 6b: Backfill around the unit with a 16-inch (410-mm) layer of material.
Key Points:
• Do not use native material to backfill if it is primarily sand; very soft or
highly expansive clay; or if it contains debris, large (> 3A-in. or 19-mm)
rocks, sharp rocks, peat, or muck. In these cases, use <_ 3 inch (< 19
mm) rounded gravel, crushed stone, or pea gravel as fill material. This
material should be washed, free -flowing, and free of debris.
• Do not backfill with sand.
Step 6c: Compact the fill thoroughly with a mechanical compactor.
Step 6d: Fill the AX-RT with water to just above the midseam flange on both
sides of the baffle.
Step 6e: Add another 16-inch (410-mm) layer of backfill.
Step 6f: Compact the fill to 2-3 inches (50-75 mm) below the midseam flange.
t
IMPORTANT:
Do not backfill around the unit
unless the lid is bolted down!

instructions for installing access risers on Orenco Tank Adapters
Watertight seams are critical for proper performance.
Step 7: Install Adapters and Risers (If Needed)
Step 7a: Install tank adapters if needed. Follow the manufacturer's instructions.
• Use PRTA24 and PRTA30 Tank Adapter Installation (NIN-TA-PRTA-2)
instructions for installing Orenco PRTA24 or PRTA30 Tank Adapters.
• Use RRFTA and RRFTA30 Tank Adapter Installation (NIN-TA-RRFTA-1)
instructions for installing Orenco RRFTA or RRFTA30 Tank Adapters.
• Use FRTA30-FRP Tank Adapter Installation (NIN-TA-FRTA-1) instructions for
installing Orenco FRTA30-FRP Tank Adapters.
• Use Tank Adapter Installation for Roth Tanks (NIN-TA-RR-2) instructions for
installing Orenco FRTA24-R or PRTA30 Tank Adapters on Roth Fralo tanks.
Step 7b: Install the access risers and any necessary grommets.
• Use PVC Access Riser Installation (NIN-RLA-RR-1) instructions for installing
access risers on Orenco Tank Adapters and grommets in access risers.
Key Points:
• Mode 3 systems require a 1-in. (25-mm) grommet in the tank's inlet riser.
The grommet must be on the same side of the riser as the AX-RT unit's
return line.
• The seam between the tank and the tank adapter has to be watertight.
• Watertight seams and penetrations are critical for proper performance.
• Before installing the riser, make sure the riser is the correct height — the
recommended riser height is 2-3 inches (50-75 mm) above final grade.
• Before installing the riser, make sure that the riser penetrations are made
at the correct height to make connections.
• Before installing the riser, make sure the penetrations are aligned correctly.
• After installing the riser, make sure all adhesive seams are smooth, con-
tinuous fillets, free of voids.
• After installing the riser, make sure the adhesive is set before continuing.
Step 8: Test Tank and Adapter Seams For Watertightness
Step 8a: Test the tank for watertightness if it has not been tested already.
Note: Follow the manufacturer's recommendations for watertight-
ness testing. Some manufacturers require the tank be fully backfilled
before testing watertightness.
Step 8b: Test the tank -to -riser adapter seams for watertightness.
• Use PVC Access Riser Installation (NIN-RLA-RR-1) instructions to test the
seams between the access riser, tank adapter, and tank for watertightness.
Key Points:
• Watertight seams are critical for proper system performance — all tank -
to -riser seams must all pass the watertightness test before you continue.
• Follow all applicable regulations and manufacturer's instructions for water-
tightness testing.

50 mm) above the midseam flange on both sides of the tank baffle.
Step 9b: Wait 15 minutes and then inspect the midseam flange for leaks.
There should be no drop in liquid level and no visible leakage from the seam.
Step 9c: If there is any leakage, contact your Dealer for information on
repairing the AX-RT unit.
Step 10: Install Effluent Filter
Install the effluent filter after the tank has been water tested.
Step 10a: Verify the model of the effluent filter.
• 0renco's FTS0444-36V, FTW0444-36V, and FT0822-14B filters are
the only models allowed for use with the AX-RT Treatment Unit.
Step 10b: Dry test -fit the effluent filter on the septic tank's outlet pipe.
Key Points:
• Make sure the filter is plumb.
• Make sure the filter is snug to the tank wall with enough clearance for
easy removal of the filter cartridge.
Step 10c: Secure the filter to the outlet pipe with one of the following methods:
• Glue the filter onto the tank outlet pipe with primer and glue, or
• Secure the filter with a stainless steel set screw.
Step 10d: If necessary for ease of access, extend the cartridge handle
with a longer length of 3/4-inch nominal (20-mm DN) Schedule 40 PVC pipe.
Step 11: Connect Transport Line from Tank to AX-RT
Step 11 a: Dry fit the 4-inch (100-mm) transport line and any fittings
between the outlet of the septic tank and the inlet of the AX-RT unit.
Key Point: Confirm there is a minimum fall of 1B inch per ft (10
mm per m or 1 %) from the septic tank's invert of outlet to the
AX-RT unit's invert of the inlet.
Step 11b: Glue all of the transport line pieces in place.
IMPORTANT: Do not use primer on ABS parts.
Step 11 c: For Mode 3 units, glue all of the return line pieces in place.
• Install the 1-in. (25-mm) return line between the return line port and
the 1-in. (25-mm) grommet for the return line on the tank's inlet riser.

Step 16: Complete Backfilling
Key Points:
• When backfilling, be careful not to alter the slope of any of the pipes.
Brace the pipes or place the pipes on a compacted bed and carefully
fill around them.
• Before backfilling, make sure the AX-RT unit's lid and all riser lids are
bolted down.
Step 16a: Backfill the septic tank excavation if it has not yet been done.
Follow the tank manufacturer's guidelines for backfilling.
Step16b: Backfill and compact around the AX-RT unit in maximum 12-inch
(305-mm) lifts.
Key Points:
• Do not use native material to backfill if it is primarily sand; very soft or
highly expansive clay; or if it contains debris, large (> 3/-in. or 19-mm)
rocks, sharp rocks, peat, or muck. In these cases, use <_ 3/-in. (<_ 19
mm) rounded gravel, crushed stone, or pea gravel as fill material. This
material should be washed, free -flowing, and free of debris.
• For installations in non -cohesive soils* with high seasonal water tables,
use 3/-inch crushed rock as the backfill material.
• Do not backfill with sand.
Step 16c: Compact the fill thoroughly with a mechanical compactor.
Key Points:
• The bottom of the AX-RT lid should sit 2 inches (50 mm) above final
grade.
• After backfilling, call the system's Service Provider to arrange for the
official System Start-up.
Step 16d: Be sure the AX-RT unit's lid is closed and secured.
Step 16e: Be sure the septic tank's access lids are secured.
*As described in OSHA Standards (29 CFR, Part 1926, Subpart P, Appendix A), noncohesive soils
or granular soils include gravel, sand, or silt with little or no clay content. Granular soil cannot be
molded when moist and crumbles easily when dry. Cohesive soils include clayey silt, sandy clay,
silty clay, clay, and organic clay. Cohesive soil does not crumble, can be excavated with vertical
sideslopes, is hard to break up when dry, and when moist, can be rolled into threads without
crumbling. For example, if at least a 2-inch (51-mm) length of 1/8-inch (3-mm) thread can be
held on one end without tearing, the soil is cohesive.

SYSTEMS
Technical Data Sheet
Using a Pump Curve
A pump curve helps you determine the best pump for your system. Pump curves show the relationship between flow and pressure (total dynamic
head, or TDH), providing a graphical representation of a pump's optimal performance range. Pumps perform best at their nominal flow rate. These
graphs show optimal pump operation ranges with a solid line and show flow rates outside of these ranges with a dashed line. For the most accurate
pump specification, use Orenco's PumpSelect- software.

VeriComm°
AXA Control Panels
For AdvanTex® Treatment Systems
Applications
VeriComm° AXA1 and AXA2 remote telemetry control panels are
used with simplex pumping operations —timed recirculation,
with gravity discharge —for AdvanTex° Treatment Systems.
Coupled with the VeriComm Web -based Monitoring System,
these affordable control panels give water/wastewater system
operators and maintenance organizations the ability to monitor
and control each individual system's operation remotely, with
real-time efficiency, while remaining invisible to the homeowner.
VeriComm AXA panels allow remote operators to change system
parameters, including timer settings, from the Web interface.
Typical AXA_ VeriComm° Control Panel
Standard Models:
VCOM AXA1, VCOM AXA2
To Specify...
To specify this panel for your installation, require the following:
Basic Control Logic: Two Operating Modes
• A "Normal Mode" that manages day-to-day functions.
• A "Test Mode" that suspends data collection and alarm report-
ing during installation and service.
Data Collection and Utilization
• Data logs of system conditions and events, such as pump run
times, pump cycles, and alarm conditions.
Troubleshooting and Diagnostic Logic
• Troubleshooting capabilities that can report suspected failed
components, which then trigger Alarms.
Advanced Control Logic
• Advanced control logic that activates during float malfunctions
to diagnose the situation and keep the system operating nor-
mally until servicing.
Technical
Data Sheet
Communication and Alarm Management
• Remote telemetry capabilities coupled with a Web -based
monitoring application (see VeriComm Monitoring System,
ATD-WEB-VCOM-1) for communication and alarm manage-
ment. Updating of point values (including timer settings) and
receipt of queued changes during each communication ses-
sion with host. Communication sessions that occur monthly, at
a minimum, and more frequently during alarm conditions.
• Multiple methods of communication, as follows:
Call -In to VeriComm® Host
Automatic notification to host of "Alarms," which signal
fault conditions that need to be addressed immediately
(e.g., pump failure).
Automatic notification to host of "Alerts," which signal
less critical fault conditions and which trigger the panel's
troubleshooting logic and alternative operating mode
(e.g., stuck float switch).
Automatic notification to host of "Updates," which include
alarm updates or all -clear notifications following Alarms/
Alerts, as well as normally scheduled monthly panel reports.
Manual, forced communication from panel to host to effect
an updating of point values and receipt of queued changes.
Real -Time Direct Connection to Panel
— Manual, direct connection at the site via RS-232 serial port,
to allow a local operator real-time access to detailed logged
data and the ability to change point values from a laptop.
— Manual, forced communication by local operator/hom-
eowner at the site to initiate an auto -answer mode, allowing
a remote operator real-time access to detailed logged data
and the ability to change point values.
During real-time, manual connections, software with open
architecture (and password security) is used; no proprietary
software is required. VT100 protocol allows access and control
from any computer modem (Mac or PC) with a simple com-
munication program (e.g., Windows° HyperTerminal); multilevel
password protection in panel ensures that only qualified per-
sonnel can access the panel's data.
Additional Features
• Status light indicators on the board,
including ...
— Flashing green LED for normal
operation
— Yellow LEDs for status of digital inputs
— Red LEDs for status of digital outputs
and modem activity
• UL-recognized and FCC -approved

Float Switch Assemblies
Installation, Operation and Maintenance Instructions
Model MF
o
Oreneo Systems'
Incorporated
1.800-348-9843
Installation Instructions
The float switch assembly is typically mounted in the screened pump vault or effluent screen inside of a septic or dosing tank.
The assembly is detachable without removal of the screened pump vault or effluent screen. A typical float switch assembly is
shown below.
Step 1:
Each float cable is provided with a color marker. This marker indicates the
function of the float. Make sure that your float cable color markers corre-
spond with the wiring diagram provided. If the wiring diagram does not
match your float cable marker colors, contact Orenco Systems® Inc. or
your local dealer for assistance.
Step 2:
To check for proper float switch operation, move each switch up and down
and check for interference. Remove the assembly from its holding bracket
by snapping it out of the holding bracket.

Installation Instructions (continued)
Step 3:
If any float interferes with another, the float may be adjusted by loosening
the stainless steel set screw provided in the float collar. Using a phillips
screwdriver, slowly back the screw out of the collar to a point at which the
collar may be adjusted. Be careful not to back the screw completely out of
the collar. Carefully rotate the collar on the stem until the float switches can
move freely past one another. Tighten the stainless steel set screw and
recheck.
Warning: Be careful not to alter the the tether lengths of any of the floats.
Alteration of the tether length may affect proper operation of the float
switch assembly.
Step 4:
Check the float settings with the project plans and specifications. If the set-
tings need to be adjusted, loosen the set screw as described in step 3.
Adjust the float switches to the desired level and tighten the set screw.
Make sure float level settings do not violate any state or local regulations.
Note: The float stem provided is the maximum length possible without
interfering with the pump minimum liquid level or screened pump vault
intake ports. Never lengthen the float stem without prior approval from
Orenco. Lengthening of the float stem will void the warranty.
Step 5:
Replace the float switch assembly in the holding bracket. Make sure the
assembly snaps fully into the bracket.
Step 6:
To allow for easy removal of a float switch assembly, a 1" diameter handle
may be added to the top of the float switch assembly. Measure the distance
from the top of the float switch assembly up to about one foot from grade
level. Cut a 1" diameter PVC pipe to the measured length and glue it into the
handle.

Installation Instructions (continued)
Step 7:
When used with an Orenco electrical splice box:
Push the level control wires through the watertight cord grips into the
electrical splice box. Leave an adequate length of electrical cable coiled
inside the riser to allow for easy removal of the pump and float switch
assembly. Do not remove the colored markers or the paper tags from the
float cables, and do not try to thread the markers and tag through the
cord grip. Tighten the cord grips by hand, not by tool, then test the tight-
ness of the cord grips by tugging on each cable. A cable is secure when
the cord grip is tight enough to prevent slippage. Adequate lengths of
cable should be left within the splice box to allow easy removal for future
disconnecting and resplicing.
Note: See the splice box instructions (EIN-SB-SB-1) and
corresponding splice box diagram for connection instructions.

Maintenance Instructions
Orenco Systems"
Incorporated
1-800-348-9843
During the annual inspection, follow the testing procedures provided to ensure that the system is operating properly. If a float is
found to be faulty, either during the annual inspection or during troubleshooting after an alarm condition, see the section below
titled Removing and Replacing Inoperative Floats.
Removing and Replacing Inoperative Floats
Important: Before doing any work either on the wiring to the level control floats and pump in the vault or in the pump control
panel, switch the circuit breakers in the panel to their "OFF" positions; then switch off the power to the system at the service
entrance panel.
1. Remove the float assembly from the vault.
2. Using a Phillips screwdriver, remove the stainless steel screws from the splice box lid, being careful not to drop the screws
into the tank. If the splice box was submerged, or if there is a crack in the conduit, there may be water in the splice box. If
this is the case, remove water from the splice box with a syringe, sponge, or other appropriate method. Loosen the cord grip
at the splice box and verify the appropriate splice for the float. Unscrew the wire nuts and remove the float.
3. Remove the inoperative float and replace it with a new one. Push the float cable through the watertight cord grip into the
electrical splice box. Leave an adequate length of electrical cord coiled inside the riser to allow for easy removal of the float
assembly. Do not remove the colored markers or the paper tags from the float cords, and do not try to thread the markers and
tag through the cord grip. Tighten the cord grip by hand, not by tool, then test the tightness of the cord grip by tugging on the
cord. A cord is secure when the cord grip is tight enough to prevent slippage. An adequate length of cord should be left
within the splice box to allow for easy removal for future disconnecting and resplicing.
4. Refer to document EIN-SB-SB-1 for instructions to splice the float wire to the wire from the control panel. Attach the float
wires using the waterproof wire nuts. It is necessary to replace this wire nut with a new watertight wire nut. Always use
watertight wire nuts or heat shrink splice kits for all connections!
5. Replace the float and collar and return the assembly to the pump vault.
6. Reconnect power and test the unit.
